What are the differences between Multi Jet Fusion and Selective Laser Sintering?

Printing Process:


Multi Jet Fusion (MJF): Uses a fusing agent and a detailing agent applied by inkjet nozzles. The fusing agent promotes the absorption of infrared light, which is then used to heat and solidify the powder layer by layer.


Selective Laser Sintering (SLS): Utilizes a laser to scan and sinter each cross-section of the powder layer by layer. The laser selectively fuses the powder based on the design.


Heat Source:


MJF: Employs infrared energy to fuse the powder where the fusing agent has been applied.


SLS: Uses a laser to sinter the powder directly.


Material Options:


MJF: Primarily uses thermoplastic materials like Nylon PA12, PA11, and TPU.


SLS: Offers a broader range of materials, including PA12, PA11, and high-performance polymers like PEEK and flame-retardant materials.


Surface Finish and Detail:


MJF: Produces parts with excellent surface finish and fine details, often requiring minimal post-processing.


SLS: Also produces high-quality parts but may require more post-processing to achieve a smooth finish.


Color Capabilities:


MJF: Typically prints in grayscale, though recent advancements have expanded its color capabilities.


SLS: Generally prints in white or gray, making it easier to dye parts post-production.


Applications:


MJF: Suitable for functional prototypes, end-use parts, and small to medium production runs. Common applications include automotive components, consumer goods, and medical devices.


SLS: Ideal for complex geometries and high-performance applications, including aerospace, automotive, and medical industries.


Post-Processing:


MJF: Generally requires less post-processing, though some finishing work like bead blasting may be needed.


SLS: Involves removing excess powder and may require additional finishing steps to achieve the desired surface quality.
